Why you'll love it
Fast and fun, loaded with mounts for your gear, and ready for anything.
Are you ready to explore? Get lost and find unmissable views, enjoy sunsets and early morning mists. The Bivio Gravel is an adventure gravel frame for bike-packing, touring, exploring and gravel riding. Constructed from world-renowned Columbus Spirit triple-butted steel tubing, the Bivio Gravel delivers the distinct, smooth ride of steel that is a joy all day and over anything.
The frame features multiple mounting options across the top tube and forks for more carrying capacity, whether it be for hydration or bike-packing bags. The gravel geometry is based around our race geometry, tweaked for added stability. Cover great distances on rough terrain with a smile as you whizz down mountain passes, through canyons, or simply wave to patrons on a canal towpath.

Built by hand with premium Columbus steel for a better ride
The unpassable is passable. We worked with Italian steelmaker, Columbus, to create a set of custom-shaped tubes using Spirit and Spirit HSS. Our aim was to balance performance and comfort. The custom-rolled top tube is made from Spirit and is ovalised for an improved strength-to-weight ratio. The seat stays use an elliptical shaped tube, orientated according to the specific direction of stress to maximise comfort.
Top tube mounts
The Bivio Gravel features top tube mounts to provide more options for storage or fuelling strategies.
Confidence in your control
The head angle and wheelbase are tuned to give you stable handling over twisty roots and rocks. The 44mm head tube improves control and performance, whilst the length is kept similar to our performance road models to give you more of a performance-focused position compared to that of our touring and utility bikes.
Premium utility fork with multiple mounts
The ultralight, carbon utility fork provides not only stability and control, but three mounts for a front rack, bottle cage, or a multitude of bags that are designed for this mounting system, giving you accessible storage on big days out on the trails. Developed by Condor, the 400g carbon monocoque fork features a carbon steerer, internal cable routing, and discrete mudguard mounts.
Explore and grip, whatever the surface
Nothing is off limits. Carve corners with conviction and grip the dirt as you descend wind-lashed Scottish passes or to the rich clay soils in Granada, Spain. The frame boasts 43mm clearance and is 650b compatible, too, should comfort be your focus. Or choose 40mm tyres from our favourite tyre brands for a race-ready setup.
Rust inhibiting treatment
After being welded, filed and cleaned, our steel frames are dipped in a rust inhibiting treatment. The treatment provides a degree of protection, particularly inside the frame, against corrosion caused by acidic substances (including water). Read more
